hi fsl experts,
i would like to create kind of a lesion map of a cohort of multiple sclerosis patients. i was thinking about a map that shows for example areas where i.e. 80 percent of all lesions were or a kind of color coded map where the majority of lesions was located.
I was thinking of the following:
- Creat masks manually from FLAIR scans in fsl view
- registrate them on the MNI152
- combine the masks with fslmaths into one (like a summation).
I am not shure about the command, would you use the add operation?
- present the map in fslview colorcoded.
I also have some difficulties finding documentation about fslmaths, like what commands exist and how to use them, any hints?
thanks everybody, Your help is greatly appreciated.
